The Russian government is downplaying the deadly nuclear explosion suspected to be a failed missile test; Lucas Tomlinson reports.

A mysterious and deadly explosion earlier this month at a naval weapons testing range in northwestern Russia resulted in the deaths of two workers due to radiation sickness, not traumatic injuries, as officials had indicated, according to a report from an independent newspaper on Wednesday.

But on Wednesday, the independent newspaper Novaya Gazeta said two of the patients that were injured in the blast died from radiation sickness before they could be taken to Moscow for treatment.

“Two of the patients did not make it to the airport and died,” a person cited as an unnamed medical worker involved in their care told the paper. “The radiation dose was very high, and symptoms of radiation sickness grew every hour.”

Four male doctors and a medical worker at the Arkhangelsk Regional Clinical Hospital, located near Severodvinsk, told the Moscow Times the facility received three men around 4:30 p.m. the day of the accident who were naked and wrapped in translucent plastic bags. Health care staff at the time were only told there had been an explosion hours earlier at a military site, the Moscow Times reported Friday.

“No one -- neither hospital directors, nor Health Ministry officials, nor regional officials or the governor -- notified staff that the patients were radioactive,” one of the clinic’s surgeons said. “The hospital workers had their suspicions, but nobody told them to protect themselves.”

A hospital employee who spoke to Novaya Gazeta on the condition of anonymity said that traces of cesium 137 were detected in the emergency room area an hour after the patients were brought in, forcing the area to be decontaminated.

"Doctors and nurses used soap solutions for decontamination. The medical staff had only face masks to protect themselves," the employee told the news outlet.

The online news site, Meduza, also quoted a rescue worker who said that people who were injured by the explosion were exposed to high levels of radiation and that medical teams who treated them lacked the necessary protective gear. It also cited a doctor who treated the patients as saying that the authorities hadn't warned them about the dangerous radiation levels.

Meduza said it did not publish their real names because of the sensitivity of the issue and the report did not mention radiation levels the patients and the doctors were exposed to.

The mysterious explosion was followed by a brief rise in radiation levels in nearby Severodvinsk, a city of 183,000, but the authorities insisted the recorded levels didn't pose any danger to local residents. Russia's state weather agency, Rosgidromet, said last week that it believed radiation levels had risen up to 16 times after the accident.

Russian officials' changing and contradictory accounts of the incident have drawn comparisons to Soviet attempts to cover up the 1986 explosion and fire at the Chernobyl nuclear power plant in Ukraine, the world's worst nuclear disaster.

The Russian Defense Ministry at first denied any radiation leak in the incident even as the authorities in nearby Severodvinsk reported a brief rise in radiation levels and advised residents to stay indoors and close the windows.

Earlier this week, the Comprehensive Nuclear Test Ban Treaty Organization said that several Russian radiation monitoring stations went silent shortly after the explosion in Nyonoksa. By Tuesday they were back in operation and backfilling the data.
